Nemanja Matic is one of United’s fit midfielders for their clash with CSKA Moscow in the Champions League

But the impressive Fellaini is a blow for the Portuguese, as he picked up an ankle knock on the South Coast after the big Belgian showed he can be a big part of Mourinho’s plans with a strong start to the season for United.

Midfielder McTominay, 20, featured heavily during the club’s pre-season campaign and played in the 4-1 win over Burton in the Carabao Cup last week.

The trip to Moscow is further complicated by the face that the club’s arch rivals Liverpool are also in the Russian capital for a game against Spartak.
